Happousai Hieta

Dokutake Castle Ninja Team Leader as well as Dokutake Ninjutsu Classroom Headmaster. A schemer and a war-enthusiast who’s gained a bad reputation for being involved in numerous sinister plots for the good of his castle and its lord. A longstanding enemy of Ninjutsu Academy as well and the Headmaster especially, he’s often plotting against them, though his schemes usually fall flat.

Since his head is literally very large, he has the habit of tipping over backwards from its weight when bursting into his signature evil laugh. He also often has to remind people what his name is, since no one ever seems to get it right.
